Adjusting the Size of the Voicing

Now that the angle of the mouthpiece is corrected, test the sound of the ocarina. With the mouthpiece held in place with a coil of clay and all the finger holes covered, blow gently and evenly (like blowing a kiss). The note should sound strong. If the note disappears or is weak, the voicing is too small and will need to be made larger.

If the ocarina sounded strong with all finger holes covered, try this next test. Uncover all the finger holes and test the sound again, using the same blowing force as before, and then slightly increase it. Don't blast air into it as you would blow a coach's whistle! The note should again sound clear. If it sounds airy ("windy" and weak), the voicing is most likely too large, and needs to be made smaller.

An ocarina with a too large voicing most always sounds excellent when all the finger holes are covered. As the finger holes are uncovered, the notes deteriorate or disappear altogether. On the other hand, an ocarina with a too small voicing will sound great on the high notes, but the low notes will be soft, weak, and easily overblown. The ocarina's sound will improve (get stronger) as finger holes are uncovered.

Weak Low Notes

Make the voicing larger by adding small pieces of clay to the "shoulders" of the opening that the mouthpiece is laid into.

These added pieces of clay position the mouthpiece farther away from the beveled edge (the lip), which makes the voicing larger. Test the ocarina's sound.

Weak High Notes

One of the causes of weak high notes is the voicing being too large. To make the voicing smaller, the mouthpiece will need to be moved closer to the lip. This is done by trimming the "shoulders."

Mark the "shoulders" with a knife. Make sure the mark is parallel to the voicing lip.

Use a slot stick as a straight edge and cut off the excess clay.

Re-position the mouthpiece and test the sound.
